Joseph Kosinski‘s follow-up to his debut, Tron: Legacy, has been waffling between the title of Oblivion and Horizons. We heard that the movie would go by that latter name, but everyone kept referring to it as Oblivion, so I just kind of assumed that the change in name meant nothing. ShowBlitz is now reporting that Universal is calling it Horizons, although they claim even that’s a working title. This is more complicated than it should be.

To keep things a little simple, they also tell us that five actresses are currently rumored to take the female lead in the project. Said to be auditioning on Saturday are Jessica Chastain, Noomi Rapace, Brit Marling, Olivia Wilde, and Olga Kurylenko. Wilde has a clear leg-up over the other four, since she had a major part in Tron: Legacy, but I don’t know if Kosinski is one to cast actors simply because of past experiences.

Marling almost worked with Cruise on One Shot, and, of course, she starred alongside his cousin, William Mapother, in Another Earth. It almost seems like the two will work together at one point — I just don’t know if this is the project to bring them together. Rapace was also close to starring alongside Horizons‘ lead, only that was for Mission: Impossible — Ghost Protocol, but she chose Sherlock Holmes: A Game of Shadows instead. Chastain and Kurylenko have both worked for Terrence Malick; this has almost nothing to do with the topic at hand, but I feel as if it’s worth pointing out.

It hasn’t been said what part they’re reading for, but it’s we’ve already heard that the main character of Jack discovers “a mysterious woman in a crash-landed pod.” This encounter “sets off an unstoppable chain of events that will force him to question everything he knows.” As for Jack, he’s been described as “a man who lives in the clouds above Earth and heads to its surface to repair drones that essentially keep the planet safe from an alien race that has all but wiped out humanity.” The film is based on a graphic novel of Kosinski‘s, one which has yet to see a release.

None of them are bad choices, although I do wonder how the helmer of a film that wasn’t a success with critics or at the box office can get a big star in the lead, along with four young actresses contending for a major role. Maybe there’s something in here that’s bold and interesting, which will really surprise people? I must admit that all this attention has created some curiosity where none initially existed.

Horizons will open on July 19th, 2013.

Did you like Tron: Legacy, and would you want Kosinski to make more films? How do you feel about any of these actresses appearing Horizons?
